¢º Calculate required output torque (T₁) or Power (kW)
Refer to Convenient Formula for the relations among the Torque(T₁),Power (kW)
and Horse Power(HP).

¢º Calculate required output shaft speed(n2) and input shaft speed (n1) or transmission ratio
Refer to Convenient Formula for the relations among the Output  Speed ,Input Speed  and Reduction ratio

¢ºDetermine the service factor
   Refer to the CH 4-1) Load Classification and Service Factor (Sf)  CH 4-2) Service factor for selection

¢ºSelect the proper reducer size on the basis of power rating  P_in greater than or equal to P₂ X Sf
Refer to CH 7-1.Nominal Power Rating

¢º Check Thermal capacity
It is important  to check whether thermal capacity rating P_T1  exceed calculated power rating value. .If Thermal Capacities are less than Power Rating  value , you have to consider the auxiliary cooling system or select more larger reducer size. Refer to CH.7-2.Thermal Capacity

¢ºVerify permissible over hung load by referring to the instructions and values specified on Over Hung Load

If the over hung load is greater than that of allowable value ,select the next larger frame size or use third bearings with an extended shaft. You have to consider that over loads are caused by low transmission ratio, high force of interia, braking, higher power than required and other dynamic and static loads.
